SIT is a freeware utility that displays the current Swatch Internet Time in your icon tray, and has a built-in time conversion tool. Also available for WindowsCE!

Internet Time is a new scheme designed by Swatch (yes, the watch-makers) which divides the 24 hour day into 1000 "beats", measured from midnight in Biel, Switzerland. Because the Internet Time doesn't change between timezones, the Internet Time is the same all over the world. See www.swatch.com for more information.
